[R] Overplotting in GGPLOT

[Nick Duncan]

Dear All,

I am struggling to jitter the labels in this plot:

p<-ggplot(centbev,aes(x=bet,y=eig,label=rownames(centbev),colour=res,
size=abs(res)))+xlab("Betweenness Centrality")+ylab("Eigenvector
Centrality")
p+geom_text()+labs(title="Key Actor Analysis AD FD Network")

When I try this without jittering I end up with labels that I cannot
distinguish, when I try it with, I get a circular spot behind the
label which makes it illegible. I  want to make the labels (which are
numeric) legible.

Many thanks for any guidance.
Nick
